MAI L-BAG STAPLE.

SPECIFICATION forming part of Letters Patent 'itlo. 427,923, dated May13, 1890.

Application filed May 29, 1889. Serial No. 312,603. (No model.)

To all whom it may concern.-

Be it known that I, FRIEND W. SMITH, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inMail-Bag Staples; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to Which it appertains to make and use thesame.

My invention has reference to certain new and useful improvements in theconstruction of staples for use in connection with mailbags orotherwise, and has for its object to greatly cheapen the manufacture ofsuch articles and at the same time to afford a very strong and superiorstaple.

With these ends in view my invention consists in certain details ofconstruction, such as will be hereinafter fully set forth, andspecifically designated by the claim.

In the accompanying drawings, Figure 1 is an elevation of my improvedstaple; Fig. 2,a sectional view showing the manner of securing mystaple.

Similar letters denote like parts in the several figures.

A is the body of the staple, and B the rivetshoulder. Heretoforo theends of the staple have been turned or milled down in order to form thisshoulder; but, in order to permit of th1s,,,very heavy wire had to beused, and

this materially increased the weight of a mail-bag. Again, the turningor milling down of the staple-ends to form the shoulder is an operationboth tedious and expensive, and the object of my present invention is toproduce a more desirable article at a less cost. The shoulder B isswaged up from the wire which forms the stock of the staple-body, thusaffording a staple of uniform gage throughout on each side of theshoulders. I form the upper face of the shoulder with a re-enforce a, inorder to afford great strength.

It is in connection with amail-bag that the great advantage of my stapleasserts itself, for the metal-bound locking-strap of the bag does notdragon the latter, but upon the upper surfaces of the shoulders B, thusin a great measure obviating the wear on the bag.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A staple made from wire having near the ends peripheral shoulders swagedup from the stock of the staple, the latter being of uniform gagethroughout on both sides of said shoulders, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

FRIEND IV. SMITH.
